About this model

On makersworld there is a low drag spool holder for the Aliexpress drybox. The problem was that the Sunlu spools don't fit to well. I made an extension to make those spools fit in there. Just print them twice. And use them for the spools with a bigger hole. The original parts you can find here The maker don't want a remix of it but this is just an add to the design.
